INVALID-BED.

To all whom it may concern:

Be it known that I, FRANK MILLER, a citizen of the United States ofAmerica, residing at St. James, in the county of Charlevoix and State ofMichigan, have invented certain new and useful Improvements inInvalid-Beds, of which the following is a specification, reference beinghad therein to the accompanying drawing.

This invention. relates to invalid beds, and the primary object of myinvention is to furnish a bed wit-h a sectional spring frame, one of thesections of said frame being ar ranged, as will be hereinafter setforth, whereby it can be placed at an inclination relatively to theother section of said spring frame, to comfortably support an invalid ina desired position, either for reading, resting or operating purposes.

Another object of this invention is the provision of positive andreliable means for safely adjusting a portion of the spring frame toinsure comfort of the occupant of an invalid bed, the adjusting beingaccomplished with little exertion and in a manner that is not injuriousto the occupant of the bed.

A further object of this invention is to ac complish the above resultsby an invalid bed that can be advantageously used in hospitals,sanatoriums and private residences, the bed being inexpensive tomanufacture, durable and highly eflicient for the purposes for which itis intended.

With the above and other objects in view, the invention resides in thenovel construction, combination and arrangement of parts to behereinafter specifically described and then claimed.

Reference will now be had to the drawing, wherein Figure 1 is alongitudinal sectional view of a bed in accordance with this invention,Fig. 2 is a plan of the same, partly broken away, Fig. 3 is a sideelevation of a portion of a spring frame illustrating a lock, and Fig. 4is a perspective view of a detached retaining member.

A bed in accordance with this invention comprises four parts, a headpiece A, a foot piece B, and side rails C that are all of the ordinaryand well known type forming parts of a metallic bed.

The reference numeral 1 denotes a stationary spring frame section and 2an ad- Specification of Letters Patent.

justable spring frame section, the latter being hinged to the former, asat 3. The spring frame section 1 is of a greater area than theadjustable section 2, the section 1 forming the foot or lower part ofthe spring frame. The spring frame section 1 has hook-shaped supportingmembers athat engage in the transverse angle bar 5 of the foot piece B.

The outer sides of the rails C, adjacent to the head piece A of the bed,are provided with sector racks 6, the lower ends of said racks providingbearings 7 for a transverse shaft 8. The ends of the shaft 8 areprovided with operating levers 9 having spring actuated locking pawls 10adapted to engage the racks 6, said levers and pawls being of aconventional form, similar to ordinary toggles. The shaft 8, adjacent tothe bearings 7, is provided with curved cam arms 11 that extend upwardlythrough straps 12 provided therefor upon the under side of the springframe section 2, said arms engaging said section whereby the section canbe raised and lowered by rocking the shaft 8.

The hinged end of the spring frame section 1 has a transverse rod 13 andthis rod is connected by a plurality of coiled springs 14 to the shaft8, through the medium of bands 15.

The spring frame sections 1 and 2 support a woven wire spring 16 and thecentral portion of this woven wire spring is reinforced by a pluralityof coiled compression springs 17, carried by a wire frame 18 locatedbeneath the spring frame section 1. The wire frame 18 has angle-shapedhangers 19 that are connected to coiled retractile springs 20, saidsprings being connected to the end of the frame section 1 and to atransverse rod 21, carried by the head piece A of the bedstead.

The sides of the frames 1 and 2, at the hinged ends thereof, areprovided with looking devices, comprising a casing 22 and a keeper 23,said casing housing a latch 2 1 that can be shifted into the keeper 23,whereby the section thereof can be locked in a horizontal planerelatively to the section 1.

To prevent the hinged end of the section 1 from being elevated when themovable section 2 is adjusted, I resort to the use of Z-shaped retainingmembers 25 in the form of bars that engage under the rails C and overthe sides of the frame 1, thereby preventing vertical displacement ofthe frame when the adjustable section 2 is adjusted.

From the foregoing it will be observed that I have devised an invalidbed for comfortably supporting an invalid or patient, the bed having amovable head section that can be easily adjusted without causing anypain to the occupant of the bed.

While in the drawing there is illustrated a preferred embodiment of theinvention, it is to be understood that the structural elements thereofare susceptible to such variations and modifications as fall within thescope of the appended claim.

That I claim is In an invalid bed, the combination with a bed havinghead and foot pieces, and side rails connecting said head and footpieces, of a stationary spring frame section having one end thereofsupported by the foot piece of said bed, an adjustable spring framesection hinged to said stationary section, sector racks carried by therails of said bed, a shaft journaled in the lower ends of said racks,operating levers mounted upon the ends of said shaft and adapted to belocked relatively to said racks, curved cam arms carried by said shaftand engaging said adjustable spring frame section whereby said sectioncan be adjusted by moving said levers, springs connecting the hinged endof Copies of this patent may be obtained for five cents each, byaddressing the Commissioner of Patents,
